Summary: Take a trip to Yellowknife, Canada to experience one of the most dangerous careers around. In unfathomably cold conditions, truck drivers haul equipment and supplies to miners in the Canadian tundra in the dead of winter on a 350-mile highway of ice.

Summary: The spring thaw is in full melt mode as the drivers get in one last lick before the ice roads close for the season. Steph Custance is the first to experience the melt as she slips and slides deep into the trees off a slick road. Meanwhile Todd Dewey is struggling with a big load of construction material over a long and twisty trail. Art Burke is not too happy when he is pressured into retrieving a super heavy bulldozer over a dangerously melting ice crossing. Reno Ward takes a risky final run just to have his truck die on the ice and Lisa Kelly is heading home when she gets an emergency call to come to the rescue before it's too late.
